Small and mighty, the ResQLink™ PLB is a full-powered, GPS-enabled rescue beacon ideal for bushwalkers, backcountry skiers, and anyone who likes to get off the beaten track. At a measly 130 grams, the ResQLink distress beacon weighs less than a couple of energy bars, and topping just 9.9cm, it's smaller than the cell phone in your pocket.
